SHUTTLE-THREADER.

SPECIFICATION forming part of Letters Patent No. 643,054, dated February 6, 1900.

Application filed February 8, 1898. Serial No. 669,565. (No model.)

T0 at when? it may concern.-

Be it known that I, ADOLF HARDMEYER, a citizen of Switzerland, residing at Goerz, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Devices for Threading WVeavers Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to threading devices for loom-shuttles; and it consists, substantially, in such features of improvement as will hereinafter be more particularly described.

Hitherto in manyinstances it has been the common practice on the part of loom attendants or operators to effect the threading of the shuttles by placing the eye of the shuttle to the mouth and then producing a suction or drawing action of the breath, by which to cause the end of the bobbin-thread to be carried outwardly through the eye. This manner of threading the shuttles requires considerable strain or exertion upon the part of the operator, and it frequently results in injury to the general health of the operator on account of the repeated inhalations of dust and fine particles of fiber which accumulated in the shuttles. Diiferent mechanical appliances have been devised for the purpose of effecting this threading operation by means of a vacuum or suction produced by a fan or suction apparatus arranged upon or in proximity to the loom; but in many instances such appliances have been complicated and 6X- pensive, besides being unreliable in use.

The object of the present invention is to provide simple and effective devices for quickly effecting the threading of the shuttle,substantially as will hereinafter more. fully appear when taken in connection with the accompanying drawings, in which Figure 1 is a side view in detail representing a fan or suction device, from which lead one or more pipes or tubes, each made up of lengths connected together, and at one or more points of which is arranged a threading device constructed and arranged in accordance with my improvements. Fig.2 is an enlarged side view, in part section, of one form of my improved threading device for loomshuttles; and Fig. 3 is a top plan View thereof. Figs. 3, 3, and 3 are enlarged detail views representing different forms of attachment to the threading device for positioning the shuttle at the timethe threading of the same takes place. Figs. 4 and 5 are respectively a longitudinal sectional view and a transverse sectional view of my improved means for catchin g or retaining the dust particles drawn into the threading device from the shuttles. Figs. 6 to 11, inclusive, are enlarged detail views representing screens of varying mesh which are employed in the screening device for the dust.

In carrying my invention into effect I connect one or more pipes A to a fan-blower or suction device B, and said pipe is led or carried upwardly (preferably) and over the different looms in connection with which the threading device is to be employed. Said pipeA is made up of different lengths or sections suitably joined or coupled together. At proper points intermediate the lengths or sections of pipe and at a suitable position over each loom I arrange a threading device of my improved construction and which is preferably comprised of a tubular section 0, having at each end a screw-threaded flange c, which screws into an opposite section of the pipe or else into a nut a on the pipe, as shown in Figs. 2 and 3. The said tubular section 0 is provided at suitable distances apart with tubular threaded nipples, into which are screwedor otherwise secured tubular nozzles c c, which are bent or turned to extend in right and left hand directions, and the ends of these nozzles are perforated-and rounded, so that they will engage the eye of the shuttle when the latter is in threading position and a suction will be produced therethrough. It is evident thata single one only of said curved nozzles can be employed, if desired. Now by placing the shuttle beneath either one of the curved nozzles, so that the eye thereof will be engaged by the perforated end of the nozzle, it is evident that by means of the back suction through the pipe A the end of the bobbinthread will be drawn outwardly through the eye of the shuttle in an obvious manner.

The fan-blower or suction device is operated continuously, so that a constant suction is produced in the pipe A, as well as in the tubular sections 0 thereof and the tubular nozzle or nozzles cc, and in virtue of the fact that there are no valves employed either in the pipe, the sections, or the nozzles a convenient and desirable means of ventilation is had for the room in which the looms and the operators therefor are located. I dispense with valves for temporarily closing the nozzles,also, for the reason that the use of the same greatly interferes with the work of the operator in having to manipulate or turn the valve each time a shuttle is inserted to be threaded, and, indeed, the operators prefer to place the shuttle to the mouth and effect the threading thereof in the old way sooner than to waste the time occasioned by the use of valves. As this old way of threading the shuttle is in j urious, however, it is extremely desirable that a quick and ready means be substituted therefor and which is furnished by the construction herein set out.

For the purpose of facilitating the placing in position of the shuttles I preferably provide the uppersurface of the tubular section 0 with flat base-pieces 0 which may be either separate from or integral with the said section and which furnish an even support for the shuttle beneath the nozzle.

As shown in Figs. 3 to 3, inclusive, I sometimes prefer the employment of means for positively arresting the nose of the shuttle in such manner that the latter can be quickly and accurately inserted in position without the exercise of much care on the part of the operator in properly locating the eye before the end of the nozzle on section 0. For this purpose I connect to the side of section 0 a hollow conical toe 0 into which the nose of the shuttle is received, and said toe is adjustable at c, by which shuttles of different sizes can be inserted and-broughtinto position with their eyes before the ends of the nozzles.

Located in the pipe A, some distance above the suction device 13, is any suitable form of device for screening and preventing the dust drawn into the pipe from passing down into said suction device. Preferably said screenin g device consists of an ordinary box D, having a removable cover at, that is secured in place by means of a suitable clamp M, and arranged across the interior of the box is a number of screens E, of wire-gauze or similarmaterial, and each screen being preferably of a greater degree of fineness, as shown in Figs. 6 to 11, inclusive. Said screens can be either rectangular or cone-shaped or of any other preferred form. Whenever required, the accum ulations of dust in the box can be readily emptied by simply removing the cover cl from the box.

It is apparent that I am not limited to the precise details of construction and arrangement herein shown and described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a pneumatic loom-shuttle threader, the combination of a straight pipe length, a branch pipe leading therefrom, and a reduced nozzle 0n the free extremity of the branch pipe said nozzle adapted to enter the eye of a loom-shuttle, said branch pipe having its nozzle extremity parallel with said straight pipe length and disposed at such a distance from said pipe length to cause said nozzle to register with the eye of a loom-shuttle when resting on said straight pipe length, substantially as set forth.

2. In a pneumatic loom-shuttle threader, the combination of a straight pipe length, a branch pipe leading therefrom, and a reduced nozzle on the free extremity of said branch pipe, said nozzle adapted to enter the eye of the loom-shuttle, said branch pipe having its nozzle extremity parallel with said straight pipe length and disposed at such a distance from said pipe length to cause said nozzle to register with the eye of a loom-shuttle when resting on said straight pipe length, and a base on said straight pipe length integral therewith for supporting the loom-shuttle with its eye engaging said nozzle, substantially as set forth.

3. In a pneumatic loom-shuttle threader, the combination of a straight pipe length, a branch pipe leading therefrom, and a reduced nozzle on the free extremity of said branch pipe, said nozzle adapted to enter the eye of a loom-shuttle, said branch pipe having its nozzle extremity parallel with said straight pipe length and disposed at such a distance from said pipe length to cause said nozzle to register with the eye of a loom-shuttle when resting on said straight pipe length, a base on said straight pipe length integral therewith for supporting the loom-shuttle with its eye engaging said nozzle, and a stop device located at the side of said straight pipe length and opposite said integral support, for positioning the loom-shuttle to engage said nozzle, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
